MIDI 4x4 USB MIDI interface

Bottom line: The Midiplus MIDI 4x4 USB MIDI interface ($49.90 on Amazon as of 2026-10-06): 4 in / 4 out gives 64 MIDI channels in one compact box; main trade-off: USB-B port, not USB-C, so newer laptops need an adapter.

SpecPicks Verdict

SpecPicks scored Midiplus MIDI 4x4 USB MIDI interface using a rating × review-volume × price-fit model applied to published specs and reviews across the audio & midi category. Midiplus's audio & midi lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Common buyer scenarios for audio & midi of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent.
